My new 24" imac is great. Faster, better & cooler (and quieter) than the old G4. A few teething probs — a couple of apps won't run; scanner driver needs updated, etc, etc. But overall, great. And — getting used to Leopard.
But of course, about a day after I'd got the ram upgraded & set up the new machine — Apple announces a bigger, better imac!!!!
hmph. . .
